The invention relates to roller bearing cages or retainers and is directed tothe procluct which may result from the practice of the method disclosed in my prior field application, now Patent No. 1,79%,634, granted 7 p formed of relatively heavy sheet metal, and

March 3, 1931. lhe present invention consists in the novel construction hereinafter set forth.

In the drawing:

Figure 1 is a horizontal section through an element of a roller bearing cage showing the first step in the formation of the same;

Figure 2 is an enlarged View of a portion of the element shown in Figure 1 illustrating a'second step in the process;

Figure 3 is across section showing a roll placed in engagement with the cage;

Figure 4 is a similar view with the retainer member in initial engagement with the cage;

Figure 5 is a similar View with the retainer bent into retaining position;

Figure 6 is a plan view of a portion of the completed cage and roll retainer;

Figure 7 is a sectional side elevation of one of the elements of the cage.

It is the primary object of the invention to obtain a construction of cage which has a considerable amount of rigidity and strength and at the same time is one which may be readily manufactured. view I have dispensed with the formation of bent flanges or tongues to act as roll retainers; and this enables me to form the cage of much heavier and more rigid stock. The retaining sockets are formed by first cutting apertures through the cage and then crimping the metal so as to arrange the original parallel side walls of the apertures in angular relation to each other and in tangent relation to the rolls. Thus a simple annulus so apertured and crimped will form an effective cage for holding the rolls in spaced relation and limit ing their radial outward movement. In order, however, to completely retain the rolls in engagement with the cage they must be forth. 1

With this object in,

held from radial inward movementwhich is accomplished by an auxiliary" f annular tongued member {as will be hereinafteijset In detail, is an annular cage member as specifically shown, of conical forml This member has formed therein preferaby by stamping, a seriesof apertures'B which, as originally formed, have parallel sidewalls;

.The apertured portionslofthe annulus are then crimped asv indicated at G which ar ranges the sides B, B thereof at anangle {to a, each other and spaced apart by a-distance less than the diameter of the roll. I may then be engaged with the'recess from the inner side and the angling "edges will be an rangedln tangent lr'elatlon and will prevent outward dlsplacement. r

To retain therolls in the cageI form a second annular member E of lighter gauge metal havingla portion for fitting within the lower end of the member'A and" provided with an outwardly-extending flange F. The Vmember E is further provided with upwardr ly extending tongues G' which are .so fashioned that when bent tothe proper angle they will extend betweenjadj'a'cent rolls and willhold the same from inward displacement. The, tongues G are initially formed with inwardly bent portions G and an out wardl-y bent portion G both arranged to clear the rolls when the member is inserted in the lower end of thecage member A." The member'E ,is'then die pressed toybend the portions G :outwardlyihto proximity with the rolls and the portions G so as'to extend between the rolls and intdcontact with the tions G" will be in 'close'proxirnity .to but member A. fThe proportions are suchthat at the completion of thi sjojper'ation theporconical member being crimped to bring the 7 .side edges of each aperture 'in'angular relation to each other spaced by less than the leave the rolls free for contact with the inner and outer face members of the bearing but will retain them in fixed relation to each other.

' What I claim as my invention is:

member, and having a shouldered engage-- ment, and tongues on said second annulus adapted to be bent intermediate adjacent rolls into proximity thereto.

2. A roller bearing cage comprising a conical member having spaced aperturestherem for receiving the rolls, the edges of each aperture being spaced apart by less than the di-.

ameter of the roll, a second annulus insert- .able through the small end of said conical ember and having a shouldered engagement, and-tongues on sa1d second annulus adapted to be bent intermediate adjacent rolls into proximity thereto, said tongues having a portion extending between and learing said rolls and bearing against said conical member. 7

3. Acroller bearing cage comprising a conical member having a series of apertures therethrough for receiving spaced rolls, said diameter of the roller and tangent thereto, a roller in said apertures, and a second an- .nular member inserted through the small end of said conical member and having a shouldered engagement therewith, said second annular member being provided with a series of tongues extending intermediate adjacent rolls, each tongue having a portion extending between adjacent rolls and with its side edges parallel to the axes of said rolls and a portion extending transversely between said rolls into contact with said first :mentioned conical member.

4. A-roller bearing cage comprising a conical portion having spaced apertures therein roll, tongue portions extending inward from the small end of said conical portion intermediate said apertures and with spaces therebetween less than the diameter of said rolls, said tongues being inwardly spaced from sa1d conical portion to provide space for sa1d rolls when in engagement with said apertures and being provided with outwardr ly extending angling portions for abutting against said conical portion.
